Note: During initial product installation and testing, the MCC

NIP CONSOLE should not be listed first in the NIPCON
list. It is preferable to list the MCC NIP CONSOLE second.
In this way, during testing, you can power off the current
MVS NIP CONSOLE (the one that is first in the NIPCON
list). This forces MVS to select the next NIP CONSOLE in
the list, which will be the MCC-attached NIP CONSOLE).
This allows IPL to occur from that console, which is the X-
terminal attached to the MCC.

Note: The NIP CONSOLE and the I/O SYSTEM CONSOLE can

be the same device. If so, only one MCC coax port is
required. If not, two MCC coax ports are necessary. Using a
single port is recommended, since there is no degradation.
Using two ports achieves no performance gain and is less
cost effective.

Ensure the NIP console(s) and/or system console(s) are defined to the
CONSOLxx member of SYS1.PARMLIB (for MVS) or other appropriate
libraries for VM and/or DOS. An MVS example follows:
